Warning PCI x1 Barely faster than USB2.
If you want real performance you are going to need to go up to at least an x8.
twice, can you please explain this a little more? I think you mean if one sticks this card into an old PCI slot, the result is barely over USB2 speeds. isn't USB2 theoretically up to 480 mb/s? help me understand; I've not been keeping up as much as you, obviously.
This is a PCI x1 card. PCI x1 has a maximim throughput of 500Mb/s USB is theoretically 480. I use eSata for backups at work. Here are some BASIC comparisons in speed:
Stats:
SBS2003, Raid5, Exchange Server, Windows Backup ~140gb (same enclosure all stats)
USB2: ~11hrs
eSata x1: ~9.5hrs (usually 10hrs)
eSata x8: ~3hrs
Nos obviously I don't have real data, but I have the exprience using the equipment.
Directron has more information on the various bus widths.
Been a long time viewer here - I finally needed to jump in.
Actually, to be blunt, your wrong, but just a little. I find it odd that you'd link an article that proved your wrongess too ^_^
USB 2.0 has a theoretical speed of 480mbits per second (Note, that is Mb/sec - megabits/sec, not MB/sec - megabytes/sec).
PCI-Express 1x has a theoretical speed of 500MBytes per second (that is MB/sec)
PCI-E 1x is over 10x that of USB - this card will max out your hard drive, and infact, is faster than the old IDE interface (by about 2x). The actual speed is inbetween the SATAI and SATAII specs.
SATAI: 150MB/sec (or ~1500Mbit/sec)
PCI-E 1x: 250MB/sec (or ~2500Mbit/sec)
SATAII: 300MB/sec (or ~3000Mbit/sec)
Thanks OP - I'm in for one!
